bit 7

bit 0

Legend:
R = Readable bit

WO = Write-Once bit

U = Unimplemented bit, read as ‘0’

-n = Value when device is unprogrammed

‘1’ = Bit is set

‘0’ = Bit is cleared

bit 7

WAIT: External Bus Wait Enable bit

(1)

1 = Wait states for operations on external memory bus disabled
0 = Wait states for operations on external memory bus enabled

bit 6

BW: Data Bus Width Select bit

(1)

1 = 16-Bit External Bus mode
0 = 8-Bit External Bus mode

bit 5-4

EMB<1:0>: External Memory Bus Configuration bits

(1)

11 = Microcontroller mode – external bus disabled
10 = Extended Microcontroller mode,12-Bit Address mode
01 = Extended Microcontroller mode,16-Bit Address mode
00 = Extended Microcontroller mode, 20-Bit Address mode

bit 3

EASHFT: External Address Bus Shift Enable bit

(1)

1 = Address shifting enabled; address on external bus is offset to start at 000000h
0 = Address shifting disabled; address on external bus reflects the PC value

bit 2-0

Unimplemented: Read as ‘0’

Note 1:

Implemented only on 80-pin devices.

bit 0

CCP2MX: ECCP2 MUX bit
1 = ECCP2/P2A is multiplexed with RC1
0 = ECCP2/P2A is multiplexed with RE7 in Microcontroller mode (all devices) or with RB3 in Extended

Microcontroller mode (80-pin devices only)

Note 1:

Available only on 80-pin devices.
